The farm's historic significance comes from its ownership by Whittaker Chambers, a pivotal figure in American Cold War politics. In December 1948, Chambers hid the "Pumpkin Papers" while awaiting a subpoena from the House Un-American Activities Committee to relinquish any intelligence stolen from the US Government by members of the Soviet spy rings within the federal government. Chambers also wrote his best-selling 1952 memoir Witness there. The property was designated a National Historic Landmark in 1988, in a somewhat controversial decision. The property remains in the Chambers family and is not accessible to the public.
